Ready biodegradability of fenitrothion in a monometric respirometry test



% Bidegradation based on ThODs

(Based on ThOD NH4): 6%

(Based on ThOD NO3-): 5%

 Fenitrothion is concluded to be not readily biodegradable under the conditions tested.

Additional information

Biodegradation of the reference material (Na-benzoate also referred to as reference control): 87%
